Abstract
People have a request to travel reliably as well as shortly, and it is needed to assess uncertainty of traffic networks for traffic management or network planning. In the stochastic user equilibrium, the random utility theory is used, but the traffic volume and the travel time that are assigned are deterministic. Thus, the previous network equilibrium models cannot assess uncertainty or travel time reliability of traffic network. In this study, we formulate a stochastic network equilibrium model whose traffic flow and travel time are random and have probability distributions. This model enables us to assess network's uncertainty or reliability. Then, we apply it to Kanazawa road network, and examine its validity or applicability.
